Title: Retransmission control system in data communication
Inventor: KAMAE NAOHIKO
IPC: H04L12/413
Filed: 2003-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To avoid the re-collision of retransmitting data in the event of collision of transmitted data in a data communication over a shared media type network using indoor power lines or radio means, etc.  <P>SOLUTION: If a transmitted packet is longer than a basic packet length of (n) slots, a system decides that data have collided. It takes an interval of (k) slots next to a slot at the end of the packet and transmits a basic packet by broadcasting for requesting the retransmitting with the next slot thereto set at a head. When a node sends a usual basic packet by itself, the system takes an interval of k slots next to its end. If there is a signal of (n) slots with the next slot thereto set at the head, it takes an interval of three or more slots from the end of its retransmit request packet, gives a sequence 1 to the next slot, and transmits the retransmitting packet with a head slot of a sequence corresponding to its own node address.  <P>COPYRIGHT: (C)2004,JPO
